Our gas class A has the main tv in a perfect location for watching it from the L shaped couch and half the dinette.
We don't have shelves next to the bed but it was our choice - we got a king bed instead of a queen. The queen has shelves. But, I installed a clear acrylic corner shelf (The Container Store) that is perfect so we are happy.
We can access the fridge and the bathroom no problem when the slides are in, though the foot of the bed is a little tough to get to. And we have plenty of room for the driver's seat.
We like the dining area on the driver's side but we never really thought about it.
I don't think there is anything in our floor plan that is a 'pet peeve.' We haven't seen one better. However, we sometimes shake our heads at some of the wiring choices made...
